In theeonstruction of buildings it isdesirnble and necessary to test the wsste-pipes, vent-pipes, and other pipes employed in the in the buildirig at in tervels of say ten stories, buiieings of higher construction requiring a double testing of the lower stories on account of the When the pipe is built up solid length after l .rth, there is at the present time no method of testing the differ- .entlengths without cutting the pipe, or

plugging it, or otherwise breaking into it, except what is known as the- Tucker fitting, which, however, compels the springing, sidewise of one or both ends etthe point of separation in order to open the pipe, one of the I open closed for testing or else it was necessary to an enlarged portion with a lateral port, which, after the testing was completed, was closed by a plug, all of which was very unsightly and cumbersome. With these old methods it is very often necessary also to remove portions of the pipe and lay the same lengthwise on the floor, thereby causing great inconvenience, especially where the house is occupied. The new fitting," which forms the subjectmatter of my invention, avoids-these difficulties, and provides means-for testing a. pipe with"-v out removing any portions thereof, end without requiring the same to be sprung sidewise as with the Tucker fitting"-, and

be i time and. with; less expense than has heretofore been possible. i i

Referring to the drawings, my inventioncomprises an elongated sleeve 10 having its lower end internally threaded along the tapered portion '11 in-upward direction. The said thread is, therefore, not a. running carried out'in less or pipes with the ends being ]then .P P p thread, but a standard pipe thread, as is customary with such threaded iron pipes. The sand sleeve 10' is also provided above the thread 11 with another thread 12 oppositelytapered, as shown in F ig. 1. In the process of erection of the building,

a lowerpipe 13 is threaded into the threaded portion ll'of the fitting 10, and anupupper pipe having at its lower end a thread 15 adapted to engage the thread 12 of the sleeve 10. The calking 16 in the hub 17 of the sleeve 10' is not put in place until after the testing has been made in the pipes 14 and in the upper lengths connected there,

ing a tight joint between the pipe 141 and with. The construction of the pipe system above the pipe 14 is continued to as high an elevation as may be' desired, in the position shown in Fig. 1 by means of a pipe clamp.

or other suitable support. A ring 18 1s secured stationary to the low-er end of the pipe 14 by means of a screw 18, the pipe 10 sliding over the-said ring during the test: ing, and when the system is completed, makthe p1pe10 for the purpose of preventing place on the the packing 16 from entering the pipe 10.

When the test is to be made, after the pipe.

l lis in position and the upper lengths of pipe are erected, the sleeve 10 is -unscrewed from the pipe 13 and raised by hand ifrom the pipe 14: until the thread 12 engages the. thread 15.

pipe 14 in the positionshown in Fig. 2, and is retained suspended on the said pipe by engageme tending into the pipe 13, shown in dotted lines, is now inserted in the exposed lower end of closes the lower 'end of the sleeve and of the pipe 14. Water is now admitted from any suitable'source into the pipe 14, and the pipe system above it, and the test is observed, a

convenient method of filling the house 'sys tem being to connect a water-supply pipe to the valve carried by the plug 19. When the test is completed, and it is desired to discharge the water contained in thepipe 14' and the upper lengths of pipe, the valve 19 is opened, and thereby the water isdis- 55 r p 14 is then put in place, that is to. say, it is slipped into the sleeve 10, the said The sleeve 10 is then screwed in p t of the threads 12" and 15. which make a water-tight connec. tion.

In Figs. 1 and 2, I have shown a pipe '13 .0

which is connected to the lower end of the fitting, but, if desired, a cast-iron pipe'ha'v; ing a hub or a T or any suitablefitting may be employed, it being immaterial whether the lower pipe be the one required to be" calked to the sleeve after the. test or screwed thereto. The sleeve 10 remains a permanent I partof the pipe line, and the latter may length of superposed pipe. It is advantageous not only when the plumbing system is erected as a whole in exposed conditionbe; fore the inclosingof the'sa'me in brickwork" orplastenbut'it is also convenlent for testing isola'ted lengths of ere'cted'pipes, where it is necessary to i at any time be tested in the manner descri ed, 'The sleeve-described provldes a convenlent and ready means of testing any desired test such lengths independ' i L ently of, others, and because of the brick and other inclosing material being ready 5' applied to that particular stretch 'of pipe; 'Thisis'especially true in connection with buildings of steel construction, wherein the whole framework of the'building is erected; a

pipe 22 is removed by hand from the cou-.'.'-'

pling 26, and is lowered into the T. A test-- ing fitting 27 provided-with a. plug, valve and pipe similar to that of the testing fitting 19 is then screwed into .the coupling 26, thereby closing and making a Water tightconnection at the exposed end ofthe 1pc,

In this position the same isteste as thecast-iron form of v riorly threaded for ily tested at pointed out with reference to Figs. 1 and '2, after the est is completed, the tes in is removed. the pipe 22 is a -n T is calked to .6. is provided, which In Figs. 5 and (3,)TI have shown a further modified form of construction as applied to}; pipe, a fitting 28 being prdvided having its lower QIidiQ-i) of smaller diameter than the upper-end, so as, to fit into a hub 3101 a lower length of pipe 30. The lower end of the said pipe 28 is intereceiving the testing fitting 33 shown in Fig. 6, the said pipe 28 being held. in positionduring the testing on the pipe 32 by means of calking 32', which is easily removed by tapping after the test. This fitting is a very convenient form for leader lines where the pipe runs straight up through the building for a considerable height, permitting the same to be readdili'erent portions thereof, and it a damaged length of pipe is to be removed, this may be done without necessitating the removal of several others.

In ig. 7, I have shown an improved cast-iron T 34-, which may used in the unscrewed from the construction shown in Figs. 3 and a, in place of the threaded T 20, having its end adapted to be calked into a fitting or length.

to a roof connection. A pipe 38 similar to the pipe 28 -struction shown in Figs. 1 and 2 in inverted is being calked, after which the screws are i p n packed with oakum. If clamp may be used instead of the screws 34. The screws are then tightened against the pipe and the joint is run withlead. This fitting may, if desired, be made of the standard size pipe length.

In Fig. 8, I have applied to a system of piping having a discharge-pipe 35 and a vent-pipe .36. It will be seen ,that with this construction it is only necessary to employ one pipe 37 connecting the vent-pipe to the T, whereas heretofore it was necessary to employ right and left nipples and right and left couplings, and a right nipple, to enable the same to be tested thereafter. It was also necessary the joint is that there be a certain amount of give or spring between carried back into" the vent-pipe and the T, the proper connection;

shown my invention as the fitting, the ion run-;

for any inac desired, a pipev position. The roof 42 has an opening through which the last length'of pipe 43 projects upwardly. It is necessary to carry the discharge end to a considerable height above the roof, however, and it is also neces sary to' make a tight connection between the flashing ed on the roof and the pipe 43. To this purpose, the pipe 38- is threaded onto the upper end of the pipe 43 after the flashing is in place around the said pipe, and the upper length of the pipe i5 being then screwed into the upper end of the pipe In Fig. 9, the principle of my invention [Y1 isja'pplied shown in Figs. 5 and? has a contracted end '89 and internally tapered threads 40 and 1' 41, the same being substantially the con- 38, the saidpipe daentending the desired height above t e roof. By reason of the pipe 38 thus overlapping the flashing, a secure protection is afforded against the in gress of rain or moisture or" any kind from the outside of the roof.

I have illustrated and described preferred and satisfactory forms of my invention, but it is obvious that changes may be made therein within the spirit-and scope thereof as defined in the appended claims.
